Abstract:
Various arrangements for presenting contextual menus are presented. A mobile device may be configured to provide contextual menus for control or monitoring of components. Different menus and interfaces are presented based the position of the mobile device or objects being pointed at using the mobile device. Specific objects may be designated as control markers. The objects may be recognized using a camera of the mobile device. When a control marker is recognized a specific menu or interface that is associated with the control marker may be presented to the user.
Abstract:
A method comprises determining, based on at least one radio frequency packet passed wirelessly between first and second devices using an array of plural antennas provided in one of the first and second devices, an orientation of the second device with respect to the first device and, if the orientation satisfies a predetermined criterion, controlling operation of the first device.
Abstract:
The present invention relates to a method and a control device for selecting a controlled device. The method includes: acquiring, by a control device, a first signal received strength of data that is received by each controlled device of at least one controlled device in a direct path mode, and a second signal received strength of data that is received by each controlled device of the at least one controlled device in a multipath mode; calculating a ratio of the first signal received strength to the second signal received strength of each controlled device, to obtain a signal received strength ratio of each controlled device; determining, according to the signal received strength ratio of each controlled device and a preset signal received strength ratio corresponding to the controlled device, whether the control device directs to the corresponding controlled device; and determining a target controlled device to which the control device directs, and displaying a control interface of the target controlled device on the control device. In the present invention, the control device can automatically identify and select a controlled device that a user wants to control.

Abstract:
The invention relates to a method for performing remote control of at least one function of a vehicle (2), wherein images of the vehicle (2) are captured by means of at least one camera (3.2) which is integrated into the mobile control unit (3). According to the invention, an optical signal is generated at at least one predefined position on the vehicle (2), wherein the remote control is then enabled only if the optical signal is captured by the camera (3.2). The invention also relates to a device (1) for performing remote control of at least one function of a vehicle (2), wherein a mobile control unit (3) comprises an integrated camera (3.2) for capturing images of the vehicle (2). According to the invention, a signal-generating unit (2.1) for generating an optical signal is arranged at at least one predefined position on the vehicle (2), and the vehicle (2) comprises at least one functional unit (2.2) for controlling the at least one function, wherein the functional unit (2.2) is embodied in such a way that the remote control is enabled only when the optical signal is captured by means of the camera (3.2).
Abstract:
A method of selecting a light source among a plurality of light sources by means of a remote controller includes the remote controller: instructing, by omnidirectional transmission, the light sources to each transmit a directional signal comprising a code, which is unique for each light source; - receiving the directional signals from the light sources; and selecting one of the light sources on basis of the received directional signals. Furthermore, the method includes: generating, remotely of the light sources, codes to be transmitted by the light sources; and - the remote controller instructing each one of the light sources which one of the remotely determined codes to transmit.
